Speed detecting method and speed detecting apparatus

Abstract

A speed detecting method, applied to a speed detecting apparatus comprising a distance computing apparatus and a speed computing apparatus, the speed detecting method comprising: (a) computing an object to be detected distance between the speed detecting apparatus and an objected to be detected via the distance computing apparatus; and (b) computing a moving speed of the object to be detected according to the object to be detected distance via the speed computing apparatus.

What is claimed is: 
     
         1 . A speed detecting method, applied to a speed detecting apparatus comprising a distance computing apparatus and a speed computing apparatus, the speed detecting method comprising:
 (a) computing an object to be detected distance between the speed detecting apparatus and an objected to be detected via the distance computing apparatus; and   (b) computing a moving speed of the object to be detected according to the object to be detected distance via the speed computing apparatus.   
     
     
         2 . The speed detecting method of  claim 1 , wherein the speed detecting apparatus further comprises a light emitting device, wherein the step (a) controls the light emitting device to illuminate the object to be detected before computes the object to be detected distance. 
     
     
         3 . The speed detecting method of  claim 1 , wherein the distance computing apparatus uses laser to compute the object to be detected distance. 
     
     
         4 . The speed detecting method of  claim 1 , wherein the distance computing apparatus is a depth sensor which acquires image depth information and acquires the object to be detected distance based on the image depth information. 
     
     
         5 . A speed detecting apparatus, comprising:
 a distance computing apparatus, configured to compute an object to be detected distance between the speed detecting apparatus and an objected to be detected; and   a speed computing apparatus, configured to compute a moving speed of the object to be detected according to the object to be detected distance.   
     
     
         6 . The speed detecting apparatus of  claim 5 , further comprising a light emitting device, wherein the distance computing apparatus controls the light emitting device to illuminate the object to be detected before computes the object to be detected distance. 
     
     
         7 . The speed detecting apparatus of  claim 5 , wherein the distance computing apparatus uses laser to compute the object to be detected distance. 
     
     
         8 . The speed detecting apparatus of  claim 5 , wherein the distance computing apparatus is a depth sensor which acquires image depth information and acquires the object to be detected distance based on the image depth information.
